Spicoli TK

Spicoli TK generates surfaces for molecules and volumes enclosed by these surfaces. Spicoli TK can then apply properties to the surface (hydrogen bonding, polarity/hydrophobicity, charge etc.) Spicoli TK writes out these surfaces attached to the molecule, so the surface and the molecule can be visualized together.

An Example of a result obtained from a combination about modeling toolkits: conformers from Omega TK were overlayed using Shape TK while surfaces and coloring were generated by Spicoli TK.

Modeling

The Modeling suite of toolkits provides the core functionality underlying OpenEye's defining principle that shape & electrostatics are the two fundamental descriptors determining intermolecular interactions. Many of the toolkits in the Modeling suite are directly associated with specific OpenEye applications and can, therefore, be used to create new or extend existing functionality associated with those applications.
